Rev Pi Connect Modbus RTU Master Initialisation

[martinw]

Hi,

I have a control system that requires a Modbus RTU Master to communicate on power up.

The only way I can get the extended data to start transmitting on power up is to "file save as start-config" and then "tools reset driver" via PiCtory, then everything works.

Is there any other way (maybe programmatically?).

Cheers,

Martin

Hi Martin,

I'm not sure if I understood your questions correct, but you can do the driver reset via `piTest -x` programmatically.

Hi Nicolai,

I know I can probably look in the code for piTest (-x), but what's the 'C' command to do that, I have a program running that I can add the command to.

Cheers,

Found it

piControlReset();
